This National Cereal Day, explore 10 fascinating facts from our cereal archives.

1. The Perfect Flake Took 36 Tries

In 1921, Washburn Crosby’s head miller tested 36 varieties of wheat and tried many methods before perfecting a tasty Wheaties flake that would not crumble in the box.

2. “Breakfast of Champions” Was Born at the Ballpark

In 1933, Wheaties earned its legendary slogan “Breakfast of Champions,” thanks to a baseball broadcast agreement that included a large advertising sign at the ballpark. Sports marketing and cereal became a winning combination.

3. Kix Almost Became a Party Snack

During early product testing in 1937, consumers shared that they served Kix in a bowl like popcorn at a party and it was a hit!

4. Cheerios Debuted with a Different Name

Cheerios debuted in 1941 as Cheerioats;  a year later, Cheeri O’Leary, the first female mascot in the cereal aisle, was introduced. She wasn’t around long but she was perfectly timed with the rise of women in the workforce during WWII. By 1945, the name was officially changed to Cheerios.

5. Trix Wasn’t Always Fruit Shaped

When Trix debuted in 1954, it was a simple trio of raspberry red, orange orange, and lemon yellow spheres. In 1991, Trix transformed into fun, fruit-shaped pieces including red raspberry clusters, yellow lemon wedges, purple grape clusters, green lime balls, and orange wedges. These fruit shapes became an iconic feature for Trix lovers in the 90s, and while they disappeared in 2006, they returned in 2018 due to fan demand. 

6. Lucky the Leprechaun was Replaced (Briefly!)

In 1975, Lucky the Leprechaun was briefly replaced – at least in New England – by a different mascot, Waldo the Wizard. Friendly but forgetful, Waldo spent each TV commercial searching for his misplaced Lucky Charms. Although the character brought a different charm to the screen, within a year, Lucky reclaimed his spot on every box of Lucky Charms.

7. Honey Nut Cheerios Has Held the Top Spot for 17 Years

Since its debut in 1979, Honey Nut Cheerios grew in popularity to become Cheerio’s best-selling flavor, a title its held since 2009. Over the years, more than 50 additional flavors have been released, including earlier editions like Frosty O’s and Cinnamon Nut Cheerios, which helped pave the way for its success.

8. Chex Invented a Video Game

In 1997, Chex included a video game called ChexQuest inside its cereal boxes. More than 5 million copies were distributed, even though only 40% of households owned a computer at the time. In 2019 Chex re-released the game for free!

9. Reese’s Puffs Released Ringtones

Reese’s Puffs have always been on the cutting edge of culture. In 2005, every box featured a code inside that fans could redeem for a free ringtone, blending breakfast with the rising world of mobile tech.

10. The Bakers Came Before the Squares

Before the Crazy Squares appeared on the Cinnamon Toast Crunch box in 2009, the cereal featured three bakers – Wendell, Quello and Bob, who first appeared in 1987 and sang a jingle promoting the cereal’s delicious taste of homemade cinnamon toast.

BONUS: Your Favorite Cereals Once Had Their Own Virtual Town Called Millsberry

The beloved online world of Millsberry was a browser-based virtual haven for cereal fans that ran from 2004 to 2010. Players created their own characters and explored a colorful town inspired by their favorite cereals, playing mini-games to collect in-game items and prizes along the way.

Adventurers could visit places like Buzz Bee’s Greenhouse, the Cookie Crisp Factory and the Trix Toys & Games store, or head to the arcade to play games like Reese’s Puffs Cereal Snowboard Slalom and Lucky Charms Charmed Life. Beyond adventuring, players could even pursue virtual careers from fashion designers to race car drivers.

When Millsberry officially ended, the game gave its players a proper sendoff where all citizens of Millsbury graduated and could download a commemorative yearbook filled with screenshots, preserving memories from one of cereal’s most unique digital worlds.
